A sperm cell has a head, a midpiece, and a tail. The head contains the nucleus and the acrosome, the midpiece contains a mitochondrion, and the tail is composed of a flagellum along with dense fibers. Jan 31, 2011 · Best Answer: The sperm cell consists of a head, a midpiece and a tail. The head contains the nucleus with densely coiled chromatin fibres, surrounded anteriorly by an acrosome, which contains enzymes used for penetrating the female egg. The midpiece has a central filamentous core with many mitochondria Status: Open.

Head defects include large, small, tapered, pyriform (pear-shaped) (Pic. 3), round, and amorphous heads (formless), heads with a small cap area .
Figure 20-25. The motile tail of a sperm is a long flagellum, whose central axoneme emanates from a basal body situated just posterior to the nucleus. As described in Chapter 16, the axoneme consists of two central singlet microtubules surrounded by nine evenly spaced microtubule doublets.Bookshelf ID: NBK26914. What organelle is found in the sperm's midpiece? BREAKS DOWN ATP TO PROVIDE ENERGY. What does the mitochondria do? Which part of the sperm contains the genetic information? ACROSOME. What is in the head of the sperm that contains enzymes that break down the membranes of the egg? FLAGELLUM. A & P II Chapter 20 Male Reproductive System 91.
Motile sperm cells typically move via flagella and require a water medium in order to swim toward the egg for fertilization. In animals most of the energy for sperm motility is derived from the metabolism of fructose carried in the seminal fluid. This takes place in the mitochondria located in the sperm's midpiece (at the base of the sperm head). These cells cannot swim backwards due to the nature of .
